It's ok...seems a little too crowded, and the lettering too big. The color scheme also seems to be a bit too random, nothing really relating to each other. Try changing the eye to a different color to match that little blurt you have on the middle left, the mash-up thing.
Like wtf happend to the person who made this topic? Oh well... Why doesn't someone else make a Numb/Encore backround so we have something to look at?
